《霍比特人》和《指环王》里的中土世界的气候模型
本报讯 谁能模拟出摩多(奇幻作家J.R.R托尔金作品中的地名)的气候类型呢?英国布里斯托大学的Dan Lunt就对《霍比特人》和《指环王》中的中土世界进行了气候模拟。
在研究中,他使用超级计算机和最初由英国气象局开发的一个模型,将中土世界的气候与现代世界、晚白垩世恐龙世界的气候进行了对比。
中土世界的模型揭示,夏尔(霍比特人的家乡)的天气很像英国东密德兰,平均温度为7摄氏度,每年的降雨量约为61厘米。而在去往末日火山的史无前例的旅程中,气候也发生了变化,亚热带的摩多地区更像是洛杉矶或者得克萨斯州西部的天气。这项研究于12月6日发表在布里斯托大学的网站上。
Lunt在工作之余完成了这项工作,他希望该研究可以使人们对气候模型所提供的可能性产生兴趣。他的论文展示了气候(无论是想象中的、现实的还是未来的)可以如何被模拟,并讨论了这种模型的优势和局限,以及理解气候如何被日益增长的温室气体所影响的重要性。(苗妮) 《中国科学报》 (2013-12-09 第2版 国际)

Abstract
In this paper, I present and discuss results froma climate model simulation of the ‘Middle Earth’ of elves,dwarves, and hobbits (and not forgetting wizards such as myself). These are put into context by also presenting simulations of the climate of the ‘Modern Earth’ of humans, and of the ‘Dinosaur Earth’, when dinosaurs ruled the Earth 65 million years ago.
Several aspects of the Middle Earth simulation are discussed, including the importance of prevailing wind drection for elvish sailing boats, the effect of heat and drought on the vegetation of Mordor, and the rain-shadow effects of the Misty Mountains. I also identify those places in the Modern Earth which have the most similar climate to the regions of The Shire and Mordor.
The importance of assessing ‘climate sensitivity’ (the response of the Earth to a doubling of atmospheric carbon dioxide concentrations) is discussed, including the utility of modelling and reconstructing past climate change over timescales
of millions of years. I also discuss the role of the Intergovernmental/Interkingdom Panel on Climate Change (IPCC) in
assessing climate change, and the responsibilities placed on policymakers.……
